Pete Doherty joins Kate Moss for Xmas

The model, 33, has only been seeing KILLS man Jamie for three months yet she's been in trouble with him countless times because of her ongoing friendship with Pete.

A source close to Kate told me: "There's no doubt that Kate still has feelings for Pete. They are always texting each other.

"But to tell Jamie days before Christmas that her ex is going to be joining them on holiday is a bit of a shock.

"Obviously the Christmas invitation to Pete to Thailand has really annoyed Jamie...once again."

Last month I revealed that the couple were rowing after Jamie, 38, found out Kate was still in contact with Pete, 28.

My source added: "Kate and Pete are often in contact and she still has a strong sense of Pete in her heart.

"Hopefully Jamie will come to see Pete as a positive presence in Kate's life.

"It might be good if all three of them try and work things out while they're in Thailand."

Somehow I doubt that they'll all end up around the piano singing Christmas carols together.
